Abstract
Methods of manufacturing cathode active materials, including preparing a solution of a hygroscopic species and a reactive oxygen species, heating the solution at a temperature that is less than about 400° C. for a time sufficient for a precipitate of the cathode active material to form, and collecting the cathode active material. The cathode active materials can be used to prepare cathodes that evolve little or no oxygen during operation. The cathodes can be economically incorporated into batteries that can provide high energy density.
